[Forminator Pro] forminator and hustle pro - display issue

hello men in tights.
i am running a forminator form, inside a hustle popup.
when creating the forminator form, i set it up so some fields display next to each other. testing it, it works.
then i slap that into a popup, when building the popup, the form displays fine. after publishing it, no matter where it displays, it defaults back to thinking it's in a mobile window, and piles the fields on top of each other rather than next to each other.
here's the preview that works: https://snag.gy/VmJNH9.jpg
here's the resulting form that sucks: https://snag.gy/Dlx1EC.jpg

patrick in his infinite wisdom, gave me this jQuery bit to paste in:

jQuery(document).ready(function( $ ){
$(".forminator-custom-form-481").removeClass("forminator-size--small");
});

while it's correct, and works on his site, it doesn't on mine.

i suspect that running siteorigin on there may have something to do with this. however, i'd really like this to work... using that siteorigin theme. i have other sites built on the same theme / builder, and it's kinda a "corporate look" that replicates over different funnels.
please help?
your support access is up and running and wildly excited to allow you in.
warm regards and thanks for having a look.
